Description
A vulnerability was found in D-Link DNS-320, DNS-320LW, DNS-325 and DNS-340L up to 20241028. It has been declared as critical. Affected by this vulnerability is the function cgi_user_add of the file /cgi-bin/account_mgr.cgi?cmd=cgi_user_add. The manipulation of the argument name leads to os command injection. The attack can be launched remotely. The complexity of an attack is rather high. The exploitation appears to be difficult. The exploit has been disclosed to the public and may be used.

Inventory every dlink dns-320 firmware deployment and check each version against the affected-products list above.
Remediation status
No patch has shipped for CVE-2024-10914 yet — track the dlink dns-320 firmware advisory for a fixed release and apply the workarounds below in the meantime.
Mitigate without a patch
Stop passing untrusted input into the interpreter or shell: call the affected binary with an argument array rather than a composed command string, reject anything outside a strict allowlist of expected values, and run the component under an account that cannot reach beyond the work it legitimately does. Alongside that, restrict the management interface to trusted networks and apply the vendor's recommended configuration mitigations.
